siggen is a cool email signature generator for encrypted ansi c (confused), brainf*ck, ... signatures. Use it in combination with vi(m), emacs, mutt, pine, or what ever. (tested on Solaris, Linux and Windoze). Optimized only for geeks :-)
CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm
bookHexor use the key.txt for encoding where is saved an arbitrary text, which is used as key. bookHexor read the key.txt and notice for each character, where it can be found as an index. If you encode text each of your charakters is displayed as index.

jWaste is a Java based implemtation of the WASTE-Protocol. WASTE is a mesh-based workgroup tool that allows for encrypted, private communication between distant parties on the internet, independant of local network organization.
This is a very powerfull criptography project that basicaly can be used to transmit or store secure data and study some cipher, hash and compression algorithms to understands how it works.
GiANT is a graphical interface for computer algebra systems (OS X/UNIX/Win). Currently GiANT lets the user work with number fields via KASH, but we aim to develop it into a GUI Library to run on top of any CAS and expose any of its functions.
httpcert is an apache module, that enables apache itself to manage x509 certificates efficiently, for Client Authentications over HTTPS.Through Web-Interfaces,Clients/Webadmin can create/submit/sign certificates using In-House CA Certificate.
This project currently provides a set of modules that enable the use of smartcard based authentication & digital signature security services. It also interact with the OpenCA project to provide a smartcard-based PKI.
NAC is a collection of tools for cryptography. The goal is to provide simple-to-use crypto tools (like an OTP, String and number generator, public key algorithm...) you can use under Linux, Windows...
OODDSS is a system that provide digital signature and verification for ELF executables and libraries in GNU/Linux
systems.
The goal is to be fast, transparent for the user and simple to administer and distribute the signed packages.
Lanchat is a Client/Server instant messenger chat service for network/internet use. Builds upon the many features of modern IM environments while implementing some unique ideas. Supports text formatting, blocking/banning, direct connections and much more
Development area for GNU/Linux 2.6.x for the KS8695 ARM SoC. Covers kernel patches, drivers for serial, Ethernet, PCI, GPIO, watchdog subsystems, and drivers for optional PCI based devices such as USB, WiFi, WiMAX, IPSec, SSL, and RSA devices.
Set of tools needed to setup and maintain encrypted partitions under unix systems (initially linux). Especially helpfull when doing root device encryption. Features xml configuration, multiple users, usb "tokens" (usb mass storage) and key hierarchy.
This proyect is an implementation of OpenPGP (RFC2440) written entirely in Java. It let's you sign, encrypt, decrypt messages and files, using public key cryptography.
Cryproc is module for the Linux kernel 2.6 which allows user space programs to access the kernel's CryptoAPI functions via a file called "cryproc" created in the /proc filesystem.
AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.
SharedSecret is a program used to negotiate a shared secret (password) by two hosts in secure way over the Internet. The software is written in C, based on client/server architecture with initial intention to run on POSIX-Compliant Operating Systems.
